Could the developers please outline, point by point, the precise hoops we need to jump through to get category intersections on Commons? New hoops seem to have been introduced during the currently discussion.
Please make an unambiguous list of the hoops Commons will be required to jump through before this feature can happen, so it's actually clear to all and we're all working from the same page, rather than trying to guess what shrubbery you'll be demanding next.
Different implementations have different hoops associated with them. As long as there's no concrete implementation, there's no definitive list of these hoops, only vague generic hoops that apply to any kind of category intersection and hypothetical hoops based on hypothetical implementations.
Like Aryeh said, Neil is currently working on a concrete implementation of category intersections. Only when that implementation is complete (or at least close) will it be possible to provide the definitive, specific and unambiguous list of requirements you asked for.
